Guide/Door Pump

A door pump is an automated machine consisting of at least 3 Mechanized Airlocks, some automation or similar way of timing, and liquids or gases to move.

Theory
When an airlock opens, it creates a Vacuum where it was, therefore sucking in any nearby gasses or liquids, and when it closes, it will push the elements inside of it out. A Door Pump chains multiple Doors together to transport Elements from one side to another, usually used to keep a Geyser from overpressurizing. See Geyser Taming for more info.

Cycle:
 * The first two doors may open at the same time. Sucking the element in.
 * The fist door closes, locking the element inside the center door.
 * The last door opens, letting the element out.
 * The center and last door close in succession.

Basic Design
A Timer Sensor can give an impuls, and each door can be put behind a BUFFER and FILTER Gate. In the simplest terms, the BUFFER Gate prolongs that input until the door needs to close, and the FILTER Gate cuts the signal off to when the door needs to open.

Improved Design
This design immediately uses the Timer Sensor more efficiently, removing the necessity of half the gates. Furthermore only activates it if there is enough Gas Pressure in the Geyser Room, which stops it from wasting power. However, The Design can also be used without need to power the doors.

Settings: For unpowered designs, all values ought to be multiplied by 3
 * Timer Sensor: 2 seconds on, 8 seconds off
 * Middle Door - Buffer Sensor: 4 seconds
 * Last Door - Buffer Sensor: 6 seconds
 * Last Door - Filter Sensor: 4 seconds

Liquid-controlled pump
An alternate design of pump is the liquid-controlled pump. It looks like this:



This type of door pump does the same thing as an automation-controlled one. It consists of 3 packets of liquid moving through an infinite loop, triggering pipe sensors as they move.

This could be coupled with a liquid shutoff on the bottom left of the pipe circuit to turn the pump on and off, however you must make sure that the packets of liquid are all maximum size, or they will combine when the shutoff turns on.
